FATENT @te GEORGE W. BAGUE, OF GLENMRA, L0'UIilSlIAlYLu` vnnrcnnApplication filed March 3,`

To all whom t may concern.'

Be it known that I, GEORGE W. DAGUE, a citizen of the United States,residing; at Glenmora, in the parish of Rapides and State of Louisiana,have invented certain new yand useful improvements in Vehicle Vfheels;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the. same.

The present invention relates to vehicle wheels, and is particularly Aanimprovement over the vehiclewheel disclosed in my tatent No. 1,335,939,granted April 6, 1920.

l The invention .has for its object the improvenient of the pneumatic.cushioning means associated with each spoke,.whereby to enhance theVutility and efficiency vci the structure. i

A further object is the provision of ysuch `a novel and improvedconstruction providediwith air cushions therein, for absorbling theshocks between the rirnand hub, so that the hub iioats on air to aord aneasy riding wheel, without the necessity of using pneumaticl tires whichare" subject Ato puncturesy and blow-outs. l A. Yfurther object is theprovision of.V a plunger movable along or within the spoke .with therim. and providing air cushion chambers, and a novelv arrangement for.the `inlet of air into said chambers whereby the air .will beaccumulated thereinand brought under pressure to provide the desiredcushioning action. l

A nfurther object is the provision in such a` structure of a novelcombination of the spoke, plunger movable with they rim, and a plunger.or piston-*movable with the felly and spoke, whereby any effectivecushioning. .means is provided. y

Anotherv object is the provision of means furthe attachment of Vone. endof each of Vthe links `without separate securing. means therefor. u

With the 4foregoing and other objects in view, whichy will be apparentVyas the de lscription proceeds, the invention resides in theconstruction and arrangement of parts hereinafter described and claimed,it being' understood that changes can be made with;

yFig. 1, and showing the hub, rim, tire and other parts in section andother portions in elevation.

Fig. 3 is an enlarged the lineft-B of Fig. 2.

#l is al detail view showing the posectional vdetail' on vsition of alink when attachingsame to the stud.

`at their inner and outer. ends to thehub G and felly 7, respectively,are tubular, and the telly is rigid with*` the hub, while the rim 8 ismovable inthe plane of the .wheel relatively to the hub, spokes andfelly.

Disposed for lcngitudinal sliding move ment within each spoke 10, is anelongated hollow or ltubular plungerll, and studs. or trunnions .12 areriveted or otherwisel in bosses en the opposite sides` of the plunger 11between the ends thereof and said studs outwardly through Alongitudinalslots 13 in opposite sides of the spoke .10.

lLinks 1a havetheir inner ends` pivotally mounted on the studs 12 andtheir outer en ds are pivotally connected, as at 16, to the rlm flnorder to pivotally fasten the links to the studs 12 without nuts, pinsor other separate .y securing means, each Vstud has a i bayonet `orL-shaped slot15 therein with the entrance end extending` to the .end ofthe stud. .and the tail of the slot disposed transversely of. the stud,.and the inner end of the corresponding` link has aA lug-15 projecting'into the opening of the link in which the stud is disposed. Thearrangement 1s such that when the link is rdisposed at substantiallyright angles with the-spoke, as seen in Fig. 4, the end ofthe link canbe slipped over the stud with the lug- 15 `entering the sletl, and whenthe link been .slid en thest'ud intopreper posities,

the link is swung outwardly and the lug l5 moves into the tail ortransverse portion olZ the slot, thereby locking the link on the studagainst movement oil of the stud, althrough the link can loscillate.When the outer end of the link is pivotally ,connected to the rim 8,there is no liability of the link becoming detached 'from theV stud, andthis avoids the use of a special securing member on each stud. `Thelinks 14 are disposed at the opposite sides of the wheel andlextendacross the edges of the elly 7. Said links connect the rim with the bodyof the wheel, and permit the rim and body to move in various directionsin the plane of the wheel a limited amount, but prevent relvativelateral displacement of the parts. L The plungers llbeing connected bythe links 111 with the rim 8, will be reciprocated within l the spokesdue to the relative movement between the telly 7 and rim 8.

In order exclude dust, dirt and foreign matter, sleeves v-17 areslidable on the spokes 10 to cover the slots 13, and the studs 12 e:-tend through said sleeves whereby the sleeves move'with said studs andplungers l1,

A rod 18 is disposed within each spoke, and

has its outer end secured by means of nuts 19, or the like, to thei'elly 7, and said rod extends inwardly and is provided substantiallymidway lbetween the ends 4of the spoke with a piston or plunger 20,having the pack- 'ing 21 engaging the walls of the plunger 11 on theinterior thereof, whereby to prevent leakage of air past said pistonlwithin the plunger in which thepiston works. Packing 221is also securedto the outer end of the `plunger 11 and contacts with the inner surfaceo1 the spoke 10` and the rod 18, to pre* vent leakage along the wall ofthe spoke and along the rod 18,V and packing 28 is secured to the innerend of the plunger and contacts with the innersuriace of the spoke.

Thus, four enclosedair cushion chambers are provided `within `the spoke,namely, one chamber 211 between the piston and inner end of the plunger,a second chamber 25 be tween said piston 20 and outer, end o1 theplunger 11 and packing 22, a third chamber4 26 between the outer end ofthe spoke 10v `and the outer end ofthe plunger 11 and packing 22, and alfourth chamber 27 between the inner end ofthe spoke and the inner endof the plunger 11 and packing`23. These chambers are enlarged orelongated or con- "tracted as the plunger l1 and spoke 10 reciprocaterelatively to oneanother, whereby "to providethe cushioning action.

In order to render the .cushions moreef ective, means is provided foradmitting air.

Thus, the studs or trunnions 12 have air in-v "Vlet ports 28 leadingfrom the atmosphere to `the interior of the plunger 11, and so arrangedthat the ports28 move to the opposite sides of the piston 20 as theparte re- "what is claimed as new 'is :L7/racers ciproato relativelyY toone another. fllaecl: valves 2f) of any suitable kind provided withinthe ports 28, to prevent the escape oi air. thereby trapping it lwithinthechambers 211 and25. 4 Y

It is also `preferable to provide rubber or similar outliers o0 on thcinner neriphery ot the riin 8 for the contact o1 the outer ends oli therods 18, should the movement ofthe parts be excessive,` such as when theair pressure low after the'wheel has been at a standstill For a periodfot time.

Astbe wheel rotates and is'subjected to jars and shocks, the body of thewheel in cluding the hub G, spokes 10 and telly T will move relativelyto the rim 8` therebyv reciprc` eating the plungers 11 and'spokes 1()relatively to one another. lWhen the plunger' 11 oit a spoke and the hubmove toward one another, this compresses the 'air' in the chanr bers and2T and when said hub and plun-1 "the pressure therein when the plunger11 and hub 6 separate and when this separation moves the ports128 pastthe pist-on 20, they communicate with `th'echarnber 25,`thereby causingair to be drawn into said chamber a J i V 25 in the same way trom theatmosphere,

In this manner, when the plunger 11"and piston or plunge'rrod 18reciprocate relativelyto one another, the ports 28 are alternatelybrought into communication with the" chambers 24 and 25, and the airisthus drawn into. and accumulated within said chambers to increase theinessuretherein, both to `make up for any `leakage of air and to alsoenhance thecushioning effect.
